Method of manufacturing an isolated porous material and an isolated porous material

Abstract

The present invention relates to a porous material comprising a porous wall structure defining and separating primary pores that are interconnected across its thickness dimension. The primary pores have a diameter greater than 5 μm and less than 1000 μm. The diameter of the primary pores gradually increases across its thickness dimension while their number decreases in its thickness dimension. The porous wall structure comprises or consists of secondary pores that are interconnected throughout the material. The secondary pores have a diameter smaller than 5 μm. The present invention further relates to a method of manufacturing an isolated porous material comprising the steps of: providing a substrate; applying an electrically conductive intermediate layer on at least part of a surface of the substrate; forming a surface layer on the intermediate layer by electrodeposition using dynamic bubble templating; and removing the intermediate layer from the porous surface layer to obtain the isolated porous material; wherein the step of removing the intermediate layer takes place during or after deposition of the porous surface layer. The present invention further relates to a porous material obtainable with a method of manufacturing according to the second aspect. The present invention further relates to the use of a porous material according to the first or third aspect in a chemical or electrochemical system.
